I use for TOAD the development as the oracle IDE like most people. When I’ve heard about oracle sql I was wondered, first of all it is developed by the oracle itself, second it’s free :)The first version of the product was bad, I was unable yo use it properly, but with the patch 2 it is much better. I suffer TOAD a lot while writing pl-sql. I am not feeling very comfortable without intellisense, and Oracle Sql Developer does that great.

Editing a stored procedure
Intellisense on table names, table columns, procedure names, packet names
